              Specimen Cutting Die

The weight of water vapours absorbed by a sample of leather is determined by fixing a circular piece of leather over a cylindrical cavity in a metal container having distilled water inside it. The test specimen is held firmly against the lip of the cavity and allowed to come in contact with the vapours left off by the water for a specified period of time. The gain in weight of the test specimen because of absorption of vapours by it is determined, from which the value of water vapour absorption is calculated.
